Specification of Letters Patent.

Application filed November 231905., Serial llo- 288,740.

To a/ZZ whom t may concern: y

Be it known that I, HENRY RICHARDSON, a subject of the King of Great Britain, residing at New York, in the county of New York and yState of New York, have invented new and useful Improvementsin Automatic Weighing-Machines, of which the following is a specification.

This invention relates to automatic weighing-machines, the ,object of the invention being to provide an yeffective apparatus of this character which is less in height than machines of corresponding type, by virtue of which I can successfully adapt the improved machine to conditions which are not possible with certain automatic weighing-machines with which I am familiar, and this I can accomplish without affecting the accuracy of the machine or its capacity.

In the drawings accompanying and vforming a part of this specification I show certain simple forms of embodiment of invention which to enable those skilled in the art to practice said invention I will set forth in detail in the following description, while the novelty of the invention will be included in the claims succeeding said description.

Insaid drawings, Figure l is an elevation of a `wei hing-machine including my invention. F g. 2 is a view of the machine as seen from right in Fig. l.v Fig. 3 is a erspective View of the rsupply-controlling va ve. Fig. i is a detail View of the weighing bucket or hopper. Fig. 5 is a detail view of a modified construction. Fig. 6 is a sectional detail hereinafter more particularly described.

Like characters refer to like parts throughout the several views.

The present machine is of the same general type as that disclosed in Letters Patent No. 760,485, granted to me May24, 1904. From what has been stated it is believed that it will be understood that I provide a machine which can be introduced and successfully operated in positions Wherethe height lat my disposal is not'sufcien't to permit of the operationof other kindsof weighing-scales. I

effect a saving in height in the present case in two w'ays-one bythe construction of a bucket or weighing-hopper of novel kind and the other by stream-supplying means of a novel j-kind', 4such stream-supplying means consisting, preferably, of a hopper and valve mechanism' arranged to operate under the hopper whetherthe valvemechanism consists of one or more than one valve. I may use the two features in conjunction with each other or separately, and I will now set forth in detail the apparatus involving the same.

The weighing-machine involving the element-weighing mechanism is represented as consisting of a bucket or weighing-hopper, as

2, and a counterweighted scale-beam, as 3.' The scale-beam 3 is fulcrumedupon theframework l and carries at its innerend the weighing bucket or hopper 2. I do not deem it necessary to go into detail or the mounting of the beam on the framework and the bucket on the beam, for these points may be as customary and as indicated, for example, in the Letters Patent to which I have heretofore alluded. The framework is shown as portable, for which purpose and to -facilitate its movement from lace to place it may be mounted upon w eels, as 5. The machine, like that of the Letters Patent, is adapted especially to bagging-work, it being adapted to weigh automatically l redetermined charges, which are delivered into bags or other suitable receptacles, as will hereinafter appear. It is not essential, however,

that the machine should be applied to such particular use,

Mounted upon the framework Il of the machine at the. top thereof is a supply-hopper, as 6, under which is arranged for swinging motion a valve, as' 7. The valve 7 is shown as being of the pan type and is adapted when closed to occupy substantially a horizontal position under the outlet ofthe hopper 6. 'Ihe valve 7 may be hung exactly as has been described in the previously-mentioned Letters Patent. To it and to the framework of the machine are connected companion links 8, the latter being jointed to each other and presenting a toggle which when straightened is adapted to lock the valve shut. Depending from the toggle is a rod 49, to which is jointed one end of 'a lever, as 10, fulcrumed on the framework e. The opposite end of said lever l0 is adapted "to engage a 'toggle connected with the discharge-valve orcloser on the bucket 2 when the valve 7 is closed, so as to `bring about lthe release ofl said discharge-valve or closer, as will hereinafter more particularly appear. Connected eccentrically with the valve 7 is a pendant 11', eo-

operative with a projection, as 12, on the bucket to control the closing ofthe valve 7 and to eifect subsequently the opening of said valve substantially in the manner shown in the Letters Patent referred to. .As to LII these features l do not deem it necessary to go into detail, for they `form no part oi the present invention. Aswill be understood, they may be as disclosed in my Letters .Patent aforesaid.

The' material to he weighed is received from a stationary chute, as 13, under which the machine is bodily moved to edect the deli very or" material from the chute to the hopside oi the valve 7, the opening in the hopper designated by and the opening 1n the Valve being designated by L5. The er;- tent di these openings should be suiiicient for the' passage therethrough oi the chute. Frein this it will be u Y l that i' steae,

machine is nov-ement the chute enters the hop rollednp to the continued until n r, which it can do thU egistering openings 14 and 15, it being-understood that when the valve is open the two openings are in resister. W hen the chute i3 is centered in thenopper 6, this will indicate that the parts are in proper poy sition for weighing.

The bucket or weighing-hopper 2 in the present case is mounted. solely for rising-and'- kialling motion.

l use this language to distinguish the bucket from lthat type which tilts or oscillates when effecting the discharge of a load'. The bucket has opposite side walls 16 and 17, shown as sloping, for by sloping these walls l get a bucket' ot' suitable capacity. The sloping oi the walls may be secured in any desirable manner. ln Fir. 4 the two walls are shown as being in para lelism. The upper open side of the bucketor weighing-hopper 2 is located under the delivery end of4 the spout or hopper 6, so that when the valve 7 is o 'en a stream of material issuing from the opper will enter the bucket and will initially fall upon the inclined or sloping wall 16, which distributes it at first in a uniform manner throughout the lower portion of the bucket, the uniform distribution of the downwardly-flowing mass being continued by the said inclined or sloping walll while the load is being made up and until the load is completed, at which time, as will beunderstood, the. valve 7 is promptly shut. The discharge-valve -or closer i'or the bucket Side-,lee

is designated by 18, and it is connected for swinging movement with the counterweighted rocking member 39, mounted upon the lower outside oi the wall 16, and the weight 19a serves to shut said discharge-valve or closer 18. F rom the rocking member 1S) there extends upward the crank portion 20. to the upper end of which is connected om` end of the rod or link 21. Connected with said rod or link between its ends is a crank 22, pivotally mounted upon the bucket and presenting with the link a lockingtoggle. "lt will be assumed that the valve 7 has been shut on the completion. of a load in the weigh ing-bucket or hopper 2 and that the toggle composed oi the links S has been straightened. Yii'lhen this results, the rod Q is thrust down ward to etiect the operation oi the lever 1U. When the lever l() is operated by the downwardly-thrust rod 9, it strikes against the iliree or outer end of the link or rod 2l, constituting, with the crank 22, a toggle, so as io break the latter and release the discharge valve or closer 18, so that should the latter be not latched it can be opened by the weight of material resting upon it. The closer or discharge-valve when shut occupies an angular position ci small pitob nnd when in such relation nts against the l edge oi the inclined Lwall 23, extending downward and in1 ward from the outer end of the sloping wall l 7.

i have. shown as mounted upon the wall 23 a latch 2-, ci angular form and pivotcd in place at its angle, the latch being adapted vto automatibally by the weight oi its lower or shouldered working arm to engage under the closer or discharge-valve 18 when the latter is shut.

i have shown as carried upon the 'training' of. the machine a pivoted sticking-spout, as 25, to which a bag can be connected or under which a bag can be placed to receive the con tents from the bucket or hopper 2. The con struction is such that when the bucket or weighinghopper 2 is down, with a load therein, and when the sackingspout 25 is swung forward it can engage the tree arm or branch of the latch 24 to trip the latter and release the discharge-valve 18, whereby the mass of material in the bucket 2 can press said closer or discharge-Valve open to permit the contents of the bucket to pass therefrom and into and through the sucking-spout and into a bag or equivalent receptacle under said spout. instead` oi pivotally mounting the sticking-spout 25 l may, as shown in h'ig. 5, carry it upon a spring-plate, as 26, and by the resiliency ofthe plate can swingthe spout carried thereon in suoli wav as to cause it to trip the latch 24.

For the purpose oi"V tripping the latch 24 the spout 25 may carry a trip device, as 25. ln llig. 6 l show a modified form of tripping mechanism. ln this iigure the sackingspout 25 carries a pivotally-inounted mem- IOO ber 25h, to which is connected a trip device, as 25C, cooperative directly with the latch 24. Normally the pivoted member 25b stands substantially inthe position shown in said Fig. 6. When a sack is placed about the spout 25, the pivoted member 25b is drawn inward, thereby thrusting the tripping inember or rod 25o against the latch 24 to disengage the latter from'the discharge-control ling valve or closure 18. lI have described the supply-chute as having an opening in or its rear wall as cut away or removed. In the drawings I have shown boththe iront and rear walls of the supplychute as open or cut away. The bucket 2 in the present case depends from the scale-beam 3 and, as shown in Figs. 1 and 2, is sup orted only by two knife-edges on said scalie-beam, such knife edges being denoted byBa. The dischargevalve or closer 18 for the bucket has a. swinging motion about an axis at right angles to the axis of motion of the scale-beam. In other words, by this construction the bucket is caused to discharge its load in a direction at right angles to the direction of movement of the beam, whereby I can secure the advantages hereinbeiore pointed out.

What I claim is- 1. In .a weighing-machine, the combinaa stream of material directed into the bucket, the other Wall having at its lower end .a dependingk wall separated from the companion sloping wall to provide an outlet for the discharge or' material from the bucket, and a valve to close said outlet and to 'ht when closed substantially against said depending wall.

2. The combination of weighing mechanism including a bucket provided with a closer, and a latch for holding the closer shut, stream-supplying means for the bucket, and a sacking-spout under the bucket having means to trip the latch.

3. In 'a Weighing-machine, the combination with a beam, a bucket supported by said beam, provided with a sloping wall and with an outlet for the deliveryof a load of material from said bucket, an oscillatory valve on the bucket Jfor controlling said outlet, the axis of motion of said valvelbeing at right angles to the axis of motion of the beam, a latch to hold said valve shut, and a sackingspout underthe bucket, having means to tri said latch. i

n testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
